In the following description similar characters of reference indicatelike parts in the several figures of the drawings.

Although the main frame of this clock may be of any suitableconstruction the same, as shown in Figs. 1, 2, and 8,-preferablycomprises upright front and rear main plates 20, 21 which are connectedwith each other by horizontal bars or posts 22, two front and rear sidebrackets 28, 24 secured to the front and rear main frame plates andprojecting laterally therefrom, a horizontal bracket bar or post 25connecting the outer upper parts of the side brackets 23, 24, front andrear auxiliary frame bars 26, 27 arranged in rear of the rear mainplate, horizontal upper and lower posts 28, 29 connecting the upper andlower ends of the frame bars, and a bolt 30 connecting the front framebar 26 with the rear frame plate 21.

The numeral 3l represents the tubular hour shaft which carries the hourhand 32 at its front end and which is journaled in suitable bearings onthe front main frame plate. Within this tubular shaft is arrangedderived from the time motor which includes a coil spring 35 having itsouter end connected with the main frame and transmitting motion from itsinner end to the hour shaft by a train of gearing operating to turn thehour hand once during every twelve hours and the minute hand once duringeach hour, this gearing including a main gear wheel 36 operativelyconnected with the inner end of the Vtime spring 85, a gear pinion 37meshing with the winding wheel 36 and connected with a gear wheel 38, agear wheel 39 secured to the minute shaft and meshing with the gearwheel '36, a gear pinion 40 secured to the minute shaft 33 and meshingwith a gear wheel 41, a gear pinion 42 connected with the gear wheel 41and meshing with a gear wheel 43 on the hour shaft 31, as shown in Figs.1, 3 and 13. The gears 41 and 42 are mounted on an intermediate shaft 44which is journalcd in bearings on the front and rear plates of the mainframe, as shown in Fig. 13. Y

Retarding of the motion of this train of gearing is effected by theusual retarding mechanism consisting of a gear pinion 45 meshing withthe intermediate gear wheel 38 and connected with a gear wheel 46, agear .pinion 47 meshing with the gear wheel 46 and connected with a gearwheel 46, a pinion v49 meshing with the gear wheel 48 and connected withan escapenient wheel 56, and an oscillating pallet 51 engaging with theescapement wheel.

At its rear end the main or minute shaft 33 is provided with a shiftingcam 52 and within the main frame this shaft is provided with a star ortappet wheel having four equidistant teeth, one of which 53 iscomparatively long and the remaining three 54, being comparativelyshort, as shown in Figs. 1, 12 and 13.

On the tubular hour sha-ft 31 is arranged an hour striking or main snail57 having twelve stops or steps arranged progressively further from theaxis of this snail and corresponding to twelve hours of a day; androtatable about the minute and hour shafts is an auxiliary or chimesnail 56 which has four equidistant stop faces arranged progressivelyfurther from the axis of these shafts. These snails are operated so thatthe'chime snail 58 turns once during each hour and the striking snail 57turns once during every twelve hours, this being preferably accomplishedby a gear wheel 59 secured to the intermediate shaft 44 and meshing witha pinion 60 secured to the chime snail 5S, as shown in Fig. 13.

The numeral 61 represents the main hori- Zontal driving shaft of thechime andY striking mechanism which is journaled lengthwise in bearingson the front and rear plates of the main frame and is driven by a motorpreferably including a spring 62 connected at lts outer end with themain frame and a train of gearing consisting of a main gear wheel 63operatively connected with the inner end of this spring 62 and meshingwith a gear pinion 64, a gea-r wheel 65 connected with the pinion 64 andmeshing with a gear pinion 66 on the main driving shaft 61, as Chewn inFigs. 1, 2 and 3. letarding the motion of this train of gears ispreferably effected by the usual brake device consisting of a gear wheel67 connected with the main shaft 61 and meshing with a gear pinion 68, agear wheel 69 connected with the pinion 68 and meshing with a gearpinion 70, a gear wheel 71 connected with the pinion and meshino' with agear pinion 72, and a rotary fly .vheei 7 3 connected with the pinion72.

The bracket plates 23, 24 carry the bearings for the shaft 55 upon whichthe gear wheel 65 and pinion 64 are mounted, and is journaled inbearings in the outer parts of the bracket plates 23, 24, and the mainshaft 61 has its central part journaled in a bearing formed in the rearmain frame plate 21 and the rear bracket plate 24 while the front end ofthis shaft is only journaled in a bearing in the front bracket plate 23,as shown in Fig. 1S. As these brackets are connected at their upperouter ends by a horizontal post 25, the latter and thesebrackets form aseparate side frame unit on which. the shafts and gear wheels andpinions just described can be readily assembled and then this side framecan be connected with the main frame and the gear wheel 65 placed inmesh with the pinion 66 on the main shaft 61, thereby facilitatingassembling of the clock and reducing its cost of manufacture. Thehorizontal post, pillar or rod 25 prevents the plates 28, 24 of the sideframe from being pressed together or spread apart, thereby avoidingcramping as well as loosening of the shaft 55 in its bea-rings on theseplates.

The gear pinion 68 and gear wheel 69 are beth mounted on the sameliftingshaft 74 journaled on the main frame and forming part of themechanism for operating the chimes and striking mechanism.

The main spring 62 at times is prevented from turning` by a locking disk75 secured to the shaft 74 and a locking arm 76 having a locking linger77 adapted to engage either one or the other of two equidistant notches78 in the pe iphery of this disk. Liftingof this locking arm 76 topermit the locking disk 75 to turn is effected by a releasing shaft 7S),which carries the arm 76, a releasing arm 8O connected with thereleasing shaft 79 and provpided with a forwardly projecting releasinglinger 8l, a controlling shaft 82 provided with a tappet arm S3 adaptedto be engaged by the teeth 58, 54 of the tappet or star wheel, a triparm 84 arranged on the controlling shaft 82 and having a forwardlyprojecting trip finger 85, and a vertically swinging detent arm 86pivoted on the frame and arranged betw-een the releasing and tripfingers 81, 85 and forming part of the counting device ofthe chime andhour striking mechanism as will presently appear.

At the end of every quarter hour one of the teeth of the star wheelengages with the tappet arm 83 and turns the same so as to lift the arms84, 86, 80, thereby disengaging the locking arm 76 from the locking disk75 preparatory to permitting the spring 62 to turn the sha-ft 61 and theparts geared thereto. Upon releasing the locking arm 70 from the lockingwheel 75 a warning stop arm 87 on the controlling shaft 82 engages witha. warning pin 88 on the gear wheel 71, whereby the gearing is onlypermitted to advance far enough to carry the respective notch 7 8 in thelocking disk out of register from the locking lever 76, but when therespective tooth 53 or 54 of the star wheel clears the tappet arm 83 andthe latter swings back so as to disengage the warning arm 87 from thewarning pin 88 and the train of gearing associated therewith arepermitted to turn forwardly the required extent. TWhen the main shaft 61has completed its rotary movement the locking arm 76, as will later'appear, is permitted to drop and engage with the next following notch 78in the locking disk 75 and therebyarrest the operation of the chime andstriking mechanism.

The means for controlling the chime mechanism at the end of each quarterof each hour and the striking mechanism in accordance with the positionof the chime and striking snails is construct-ed as follows:

The numerals 89 and 90 represent main and auxiliary counting rackshaving the form of toothed segments which are are anged side by sidebelow the detent arm 86 and pivoted coaxially on the adjacent frontplate of the main frame by a pivot 91. The main rack is comparativelylong and has at least twelve teeth 92 and preferably more, of which thefirst twelve serve as counting teeth and the remainder serve merely aslifting teeth. The auxiliary rack has at least four teeth 93 andpreferably more, of which the iirst four serve 'as counting teeth andthe remainder serve as lifting teeth. In the present case the radialdistance of the two counting racks is the saine and the teeth of thesame are of equal length, but this is not essential inasmuch as thisdistance and length can be varied and still permit of obtaining theadvantageous results of this invention. The main counting rack 89 isprovided with a snail 4arm 95rwhich is adapted to engage the steps orstops of the hour snail 57 and the auxiliary rack is provided with asnail arm 95 which is adapted to engage with the steps or stops of thequarter hour snail 58. These racks when free are turned in the directionfor engaging their snail arms with the registering steps of the main and'auxiliary snails, respectively, by gravity aided by means of springs96, 97 connecting these arms with the adjacent part of the frame. Thefree end of the detent arm 8G is preferably arranged ina plane passingbetween the main and auxiliary racks and is provided on its oppositesides with detent pawls or jaws 98, 99 the former being set forward ofthe latter or nearer the axes f the gear racks so that when the mainpawl 98 engages with an intermediate tooth of the main rack then theauxiliary pawl 99 will be held out of the path of the teeth of theauxiliary rack but after all the teeth of the main rack have passed themain pawl then the detent arm 86 can drop or move farther toward theracks and engage the auxiliary pawl 99 with the teeth of the auxiliaryrack.

After the racks have been released by the detent arm and have movedforwardly by gravity and spring means, the same are again movedbackwardly the same extent corresponding to the position of therespective snails. This backward movement is produced by a rotarylifting wheel 100 mounted on the front end of the lifting shaft 7 1i andprovided with two diametrically opposite teeth or pins 101 which areadapted to engage successively with the teeth of the counting racks andreturn them step by step into their rearmost position.

By arranging the detent arm 86 above the counting racks and engaging theunderside of the same by the trip 'arm 84 while the upper side of thedetent arm engages the under side of the releasing arm 80, the countingmechanism is materially simpliiied and less power is required to operatethe chiming and striking mechanism.

Arranged in the rear of the lower part of the main frame is a chime,player drum consisting of four chiming wheels er player disks i02, 108,10ft, 105 and a striking wheel or disk 106 arranged side by side, thechiming wheels being to the main frame and the striking wheel being inrear of the chiiring wheels. T he chiming wheels are slidable lengthwiseon the main shaft 61 and at times turn with said shaft and at othertimes are held against t rning therewith. Each chiming disk or wheel ispreferably made of flat metal and provided on its peripheral edge withan annular row of player pins, tappets, or teeth 107. rlhe severalchiming disks are mounted on a hub which consists of a central bushingor tube 108 upon the periphery of which three collars are mounted, acentral collar 109, a front collar 110, and a rear collar 111, thesecollars and bushing being held together by a friction or driving lit andalso by peening or upsetting slightly the front and rear ends of thebushing against the foremost and rearmost faces of said collars. The

fin

central collar is provided at its opposite ends with annular' shoulders118 which are formed by reducing these ends and upon which theintermediate two chiming wheels 103, 104 are seated with a driving lit,and the front and rear collars 110, 111 are provided on their front andrear ends, respectively, with annular shoulders 112 upon which the frontand rear chii'ning wheels 102, 105 are securely ield by a driving titand also by peening or upsetting the end collars 110, 111 against theend chiming disks or player wheels.

The striking disk or wheel 106 is provided with an annular row of tenequidistant striking pins, teeth or tappets 114 and is mounted by adriving tit on an annular shoulder 115 on the rear end of a tubular hub110 slidable lengthwise on the adjacent rear part et the driving sha'it61. rllhis construction of the disks or wheels and hub of the chimesdrum and the disk and hub of the striking wheel is very simple, strongand durable and can be easily and economically manufactured.

The striking disk is always compelled to turn with the shaft 61 and attimes the chimes 1isks are compelled to turn with the striking diskwhile at other times the chimes disks are held against turningtherewith.

Turning of the striking disk 108 with the driving shaft is eiizected bya driving arm or index arm 117 secured to the rear end off this shaftand provided at its outer end with a forwardly projecting chime wheeldriving pin 218 ol' tubular form which constantly engages slidingly witha driving opening 11.9 in the striking disk 106 adj acent to theperiphery thereof, as best shown in Figs. 12 and 1-1. Slidable oriloating lengthwise in the chime driving pin 218 is a player wheeldriving` pin 118 adapted to engage Vith one or another oi a plura ityo1'l coupling or driving openings 120 in the rearinost chiming disk orplayer wheel 105. rllhe chime wheel driving pin 118 is yieldingly heldin its toremost position relative to the striking wheel driving pin 218by a spring 210 arranged in rear of the driving arm 117 and secured atits inner end to the hub ot the same while its outer end pressesforwardly against the rear end oit the ehiming wheel driving pin 118.The orward movement oit the latter is limited by a stop 21'? havingpreferably the Jforni ci a disk secured. to the rear end of the pin 118and adapted to engage the rear end et the tubular driving pin 218.

ln the toi-mer construction the pin 118 was rigidly attached to theindex or driving arm 117 and thereby liable to cause stubbing orainming` et' the mechanism if the hole 120 in the rearmost player wheel105 did not line up exactly with the driving pin 118 when the playerwheels were moved rearwardly for ei"- iecting ehiming action. l/Viththis new construction the pin 118, being yieldingly mounted, will recedeit a solid part ot the rearmost player wheel 105 durino' the'rearwardmovement of the player wheels engages the pin 118 inasmuch as the spring219 will give way, but when the pin 118 during its rotation with theshaft 61 comes into alf nement with a hole 120 then the pin 118 will beshot forwardly into engagement therewith by the spring 219 and cause theplayer drinn to be coupled with the shaft for producing a chimingaction.

This organi tion therefore permits the wheels to be turned at randomwithout liabilitj7 of amming the pin 118 because eventually a hole 120will line up with this pin and permit the latter to shoot into the samewith p certainty and thus insure proper functioning of the hour strikingand quarter hour chimiug mechanism.

By driving the chimes drinn an d the striking disk or wheel adjacent totheir peripherios through tl'ie i -ediui'n ci the driving pins 118 and218 a greater amount of space is available for locating the couplingopenings 120 in the ehiming nis I 105, the j )arts are more accessibleand more easily assembled, estreme j accuracy in workma ship is notrequired, power for driving the driuns and striking wheel is appliedmore ellectively so thatl a lighter spring motor can be used, and thehammers oi the chimes and striking mechanism are not liable to becomehung7 or stuck halt way during the chiming or strikopcration due to thelack ol power applied to the chiming and striking wheel, as would be thecase ir" wheels were turned by power applied adjacent to the hubsthereof. inasmuch as the linear distance of a circumferential linebecomes shorte the radius of the same decreases any inaccuracy in thelocation of; the coupling` openings 120 are multiplied as the distanceof the same from these openings to the axis oit' 'he disk 105 is reducedand it is therefore apparent that greater latitude is permitted in the'formation of these openings without liability oi" unfavorablya'llecting the working` ot the chiining` mechanism. The several disksare yieidingly held in their foremost position when tree by a spring 121surrounding the driving shaft (S1 and interposed bet veen the lront sideof the driving arm and the hub of the striking disk. In the foremostposition of the chiming drum the same is uncoupled trom the main shaftG1, :is shown in Fig. 14, and at this time the drum is locked againstturning by a locking pin 122 projecting rearwardly from the rear plateof the main frame and engagino with a locking opening or slot 128 in theIoremost chiming disk 102. In order to permit o'f readily adjusting theposition oi"- the locking pin. 122 to the locking open' this pin ismounted on an adjusting arm 1.2/1 which is capable ot swingtransverselyacres the front end of the drum and has its outer end pivoted by rivet125 to the adjacent part of the rear plate oi the drum and striking themain frame. By turning this arm on its pivot the locking pin 122 can bereadily and easily adjusted to the path of the locking opening 123without requiring extreme accuracy in manufacture in order to insureengaging this opening with said pin the instant this opening and pin arein register at which time the spring 121 pushes the several diskforwardly and causes the chiming drum to be uncoupled from the shaft 61but maintains the coupling between the striking disk and the drivingshaft 61. The rivet 125 which connects the arm 124 with the main frameis preferably made suiiiciently tight so that these parts will remainfrictionally in their adjusted position, thereby materially si1nplifyingthe construction and reducing the cost of manufacture.

The rearward movement of the chiming drum and the striking 4disk iseffected by a horizontal rock shaft 126 journaled transversely on therear plate of the main frame and provided at its inner end with an innerdepending cam arm 127 which engages with the cam 52 and at its outer endwith a forked arm 128 which engages with the front end of the drum hubon opposite sides of the driving shaft 61. The cam 52 is so constructedthat during the first quarter following each hour the same will move thechiming and striking disks rearwardly so that they are coupled by thepin 118 and held in this position long enough for the locking opening123 to move out of register with the locking pin 122 after which theinner arm 127 drops oif from this cam 52 and the imperforated rear faceportion of the foremost chiming disk 102 rides on the end of the lockingpin 122 until the opening 123 again presents itself at the end of arotation and the chiming drum is again moved forwardly into a lockedposition by the spring 121.

After the cam arm 127 drops off from the cam 52 the same hangs bygravity in a pendant position and its movement toward th-e low part ofthis cam is limited so that it cannot engage the same by a stop 129arranged on the rear side of the rear main frame plate which is adaptedto be engaged by said cam arm 127 as shown in Fig. 14. By this meansfrictional engagement of the cam arm 127 with the low; part of the faceof the cam 52 is prevented thereby avoiding wear on these parts and alsoeliminating unnecessary friction which would cause a drag on themechanism and waste some of the power of the chime and striking springand otherwise require making the latter more powerful to properlyoperate the chime and striking mechanism. Y

Below the chimes drum and the striking wheel is arranged a set of bellrods, in the present case live in number comprising four chiming rods130 and a striking rod 131. These rods are arranged preferablyYhorizontally and parallel and mounted at one end on a stationary stand132 which is supported on the clock case containing the clock mechanism.rilhese bell rods are sounded by a hammer mechanism which is actuated bythe chimes drum and the striking wheel in accordance with the presentimprovement which is construct-ed as follows:

rlhe numeral 133 represents a lower pivot rod mounted horizontally andlengthwise on the lower part of the upright bars 26, 27 of the rear orhammer frame; Upon this pivot rod is arranged a longitudinal row ofha1nmer hubs 134, each of which turns on this rod and is provid-ed withan annular groove 136.

Associated with the disks of the chimes drum and striking wheel and thebell rods are five hammer levers each of which is constructed of asingle piece of wire and bent to form a central semi-circular loop 137which is seated in one half of the groove of one of the hammer hubs andis secured therein by peening or riveting the adjacent parts of theedges of this groove over the loop, as shown at 138 in Figs. 14 and 15,an L shaped lower arm 139 extending downwardly from the lower end of theloop and provided with a hammer head 140 adapted to strike one of thebell rods, and an upper arm 141 projecting upwardly from the upper endof said loop and terminating in a brake finger 142 which is adapted toyieldingly engage a hub or collar 143 on an upper horizontallongitudinal pivot rod 144 mounted on the upper parts of the hammerframe bars.

On the upper pivot rod are fulcrumed a plurality of intermediate hammerlifting levers each of which is secured to one of said hubs 143 and hasa lower arm 146 provided with a laterally projecting pin 147 adapted toengage the upper arm of one of the hammer levers and an upper arm 148having a laterally projecting pin 149 adapted to be engaged by the teethof one of the disks of the striking wheel or chimes drum. Whenever atootn of one of these disks, during rotation of the drum or the strikingwheel, engages the upper pin 149 of a hammer lifting lever the upper armof the latter is deflected in one direction and the lower arm in theopposite direction so that the lower pin 147 of the same, by engaging`the upper arm 141 of the respective hammer lever will cause the hammerto be lifted and when the tooth of the respective disk clears said upperpin of this lifting lever the respective hammer drops into engagementwith the companion bell rod and sounds the saine. As the hammer hits thebell rod th-e brake linger 142 on the upper arm of the respective hammerlever strikes the adjacent collar or hub 143 and is yieldinglyarrestedso that the hammer strikes the bell rod with a springing blow, and asthe lifting lever drops back into its normal position the same engages arubber bumper 150 having the form of a sleeve mounted on a horizontalrod 151 which is supported lengthwise on the bars 26, 27 of the soundingframe, as shown in Figs. 3, 11 and 14.

' In this hammer mechanism each hammer lever is made from a single pieceof wire and no counter weights are employed, thereby simplifying theconstruction, and enabling a better blow against the bell rods to beobtained. Due'to the use of side pins 147 149 on the upper and lowerarms of the intermediate levers an easier sliding action of the same onthe hammer levers is secured.

The operation of this clock is fully described in the pendingapplication above referred to and the following brief review of the samewill therefore answer present reor count-ing racks 89, 90 at which timethe chiming and striking mechanism is at rest. The descent of the detentarm at this time is limited by engagement of the main pawl 98 with anupwardly facing shoulder 152 on the front end of the main counting rack.

Upon reaching the first quarter of an hour the first short tooth ortappet 54 of the star wheel will engage the tappet arm 83 and lift thearms 88, 84, 80, and 76 so as to release the locking arm 76 from thelocking disk 75 and also lifting the detent arm 86 far enough todisengage the auxiliary counting pawl 99 from the front end of theauxiliary counting yrack 90 but not far enough to disengage the itsspring 97 until its gage finger 95 engages the highest face or step ofthe auxiliary or chiming snail 58, and also permitting the main shaft 61and the lifting wheel 100 to turn. The instant this occurs the chimedrum will turn far enough to produce four strokes on the respective bellrods and then be arrested by the locking arm 7 6 engaging with the nextnotch 78 of the locking disk 7 5. While thus released the lifting wheel100 makes a half turn and one of its pins 101 engages one of theadjacent teeth of the auxiliary counting rack 90 and moves the samebackwardly one tooth, space or step so that the auxiliary detent pawl 99can again drop into engagement with the front end of this rack. Droppingof the detent arm so that its auxiliaryV pawl 99 engages with the frontend of the auxiliary counting rack also permits the ylocking arm 76 to,drop into the next notch 78 in the disk and stop its rotation, therebyarresting the operation of the chiming mechstar wheel release thelocking arm 7 6 from i the locking disk 7 5 and permit the auxiliarycounting rack to move forwardly two and three steps in accordance withthe second and third higher steps of the auxiliary snail but Stillholding the main rack in its rearmost position, whereupon the chimes aresounded twice and thrice, respectively, and the auriliary counting rackis moved step by step back into its rearward position and then thechiming mechanism is stopped. After each backward step of the auxiliaryrack 90 due to the rotation of the lifting wheel 100 the pawl 99 engageswith the adjacent tooth 93 of the auxiliary counting rack, as shown inFig. 7 and prevents the same from moving forward while the lifting wheelis out of engagement with this rack.

At the end of the first hour the fourth or long tooth 58 of the starwheel turns the arms 76, 86, 84, and 89 a greater extent so as to firstoperate the chiming mechanism for sounding the chime rods four times andthen operate the striking mechanism for sounding the striking rod once.Then the detent arm 86 is raised at this time both the main pawl 98 andthe auxiliary pawl 99 are moved .out of the path of the main andauxiliary counting racks 89, 90, as shown in Fig. 9, thereby permittingthe auxiliary rack to move forwardly four spaces or teeth and the mainrack to move forwardly one space or tooth in accordance with theposition of the auxiliary and main snails at this time. After thecounting racks have been thus moved forwardly the detent arm 86 dropsand engages its main pawl 98 with the main rack between the first andsecond tooth thereof for holding the main rack, while the auxiliary pawl99 is-out of engagement from the auxiliary rack, as shown in Figs. 5 and8. As the lifting wheel 100 now turns it first moves the main rackbackwardly one step during which the chimes are sounded for the firstquarter hour, and the auxiliary rack is moved idly. Following this thedetent arm drops sufficiently to move its main pawl98 into engagementwith the front end of the main rack and also engages its auxiliary pawl99 with the space between the fourth and fifth tooth of the auxiliaryrack. The rotation of the lifting wheel now moves the auxiliary rackback four teeth during which the first, second and third tooth cause thechimes to be sounded for the second, third and fourth quarters of thehour, and then the auxiliary rack is moved backwardly its fourth andlast tooth or space during which the striking mechanism is operated tosound one oclock.

During the first, second, third and fourth quarters of the hour thechiming disks 102,

103, 10st and 105 and the striking disk 106 are held in their rearmostposition by the locking pin 122 engaging with the imperforate portion ofthe foremost disk 102, during which time the chiming disks operate theirrespective hammers but the striking disk 10G is moved away from the pin11'9 of the intermediate lever associated with the hammer of the hourstriking mechanism, as shown in Figs. 3 and le so that the latter is notoperated. After the chiming disks have turned far 'enough at the end ofthe hour to c sound the chimes four times, the locking opening 123 ofthe foremost chiming disk 102 registers with the locking pin 122 and isinstantly engaged therewith by the pressure of the spring 121 whichpushes all of the chiming and striking disks or wheels i'orwffirdly,thereby holding the chiming disks against turning but bringing thestriking disk into line with the upper' pin 149 of the intermediatelever 1li-6 of the striking mechanism and causing the latter to beoperated by the rotation of this striking disk 100.

At the completion of each additional hour the main counting rackadvances one step further and therefore has to be moved backwardly acorrespondingly increased number of steps in order to return the same toits home position by means of the lifting wheel, but the auxiliary rackat the end of each hour always advances four steps. As the main rackincreases the number of its forward steps the first four return stepsare always taken o the main counting rack to operate the four quartersof the chiming mechanism and the remaining return steps for operatingthe striking mechanism are partly taken olf from the main counting rackand then always completed by counting the last four steps olf theauxiliary counting rack. For exa-mple, when the time is nine oclock, asshown in Fig. 4, the auxiliary rack moves forwardly four steps and themain rack moves forwardly nine steps at the end of this hour and inoperating the chiming and striking mechanism the iirst four counts aretaken off the main rack for sounding the four quarters of the hour, thenthe striking mechanism is operated nine times by taking the remainingtive counts from the main rack and adding thereto the four counts of theauxiliary rack.

This organization of chimes clock is materially simplified inconstruction as compared with the structure shown in the applicationabove mentioned, the same can be manufactured more economically, and itis not liable to get out of order.

The net result of all of these improvements combined is to prevent, asfar as possible, jamming of the striking mechanism and the bending ofparts and lockwork by the pushing of the minute hand against resistancein attempting to reset or restart the clock, and with these improvementsit is possible to turn the minute hand at random backwards or forwardsat any time, even during the process of striking of the clock, withoutmeeting with resistance or jamming, and demonstrations have shown thatit is practically impossible to disarrange the striking mechanismthrough manipulation of the minute hand with these improvements.
